current in a parallel circuit

• Parallel circuit


  A circuit that contains branches, where the current splits and passes through multiple paths
• Current flow in a parallel circuit

  1. Current splits and passes through multiple branches

  2. Current in each branch adds up to the total current leaving the power source
• Current is measured using an ammeter, which is placed in the circuit
• In a series circuit, the current is the same all the way around the circuit
• Marginal utility


  The additional utility (satisfaction) gained from the consumption of an additional product
• Total utility is the sum of marginal utility for each unit
